Welcome to our comprehensive guide on Chalcedony Quartz Gemstones. Chalcedony is the term used by gemologists as a species name for all types of cryptocrystalline quartz, including agate, chrysoprase, carnelian, bloodstone, jasper, onyx, moss agate and petrified wood. So all quartz that is not macrocrystalline, such as amethyst, citrine, rock crystal and smoky quartz, is referred to generically as chalcedony.

Chalcedony is also used as a varietal name to refer specifically to bluish-gray or lavender colored cryptocrystalline quartz. This color is sometimes called "actual chalcedony" or "chalcedony in the narrow sense". This can be slightly confusing, but fortunately, most other chalcedony is referred to by other names, such as agate, bloodstone or carnelian.
